The PSR-TRISAFE is
a safety controller that saves space and time while reducing risk and costs.
The TRISAFE can monitor an entire safety circuit, from emergency stops to
safety doors, in a machine or plant. It is rated to the latest international
machine safety standards. It has 20 safety inputs and four Category 4 safety
outputs. Using the free SAFECONF software package makes it easy to configure
the TRISAFE. TRISAFE and the simple SAFECONF software make it easy for the
designer to develop the safety project, compile it and run the simulation. The
software's drag-and-drop interface does not require any programming experience.
The designer can create or modify projects using the simulation mode to verify
programming without ever connecting to the hardware or wiring the I/O. Since
SAFECONF can be downloaded free without even purchasing the TRISAFE, the
software provides a no-risk, no-charge test drive. TRISAFE's compact size and
four Category 4 outputs reduce space requirements. The hardware is just 67.5 mm
wide, occupying 50 percent less DIN rail space than similar products available,
while still offering the same amount of I/O. Each single safety output is rated
for Safety Category 4/Performance Level "e" in accordance with EN954-1/ISO
13849-1. Other products currently available must use two safety outputs to
reach safety category 4. The designer saves 50 percent on the required safety
output point count when building a dangerous machine. Most safety controllers
require complex software with expensive licensing fees, but SAFECONF is both
simple and free.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
